Let's say that I have a folder, within my Documents folder, that has files I want no one to access without a password.

Is there a way to lock down that folder so that it's password protected / encrypted?

In fact, is it possible to password-protect any individual folder?



WARNING: CryptKeeper has recently been reported that it has a universal password bug that puts your data at potential risk. This issue may not yet be fixed in Ubuntu, use this solution at your own risk.

Debian bug: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=852751

 sudo apt-get install cryptkeeper

                                After installing, go to Applications –> System Tools –> Cryptkeeper.

                                        Cryptkeeper will automatically attach itself to the top panel

    In case you can't see the panel icon run gsettings set com.canonical.Unity.Panel systray-whitelist "['all']" and unity --replace. – Jakob Feb 17 '12 at 9:01

    Cryptkeeper received bad ratings recently on the Ubuntu software center – danza Jan 14 '16 at 14:45


EncryptedPrivateDirectory Method.

Ubuntu Official Wiki

Search for and install ‘ecryptfs-utils’ in Ubuntu Software Center:

enter image description here

After installing, go to Applications –> Accessories –> Terminal and run the command below:


enter image description here

You’ll be prompted to type your login passphrase (password), and to create one for your private folder:

enter image description here

When you’re done creating your password, Log Out and Log back in:

enter image description here

Next, go to Places –> Home Folder:

enter image description here

And new folder should be created in your home directory called ‘Private’. This folder in encrypted and password-protected. Move all your personal stuff into this folder to secure them:

enter image description here

Users without access to the folder will be denied:

You have 2 choices if you want to lock down a folder from other users

  • Encrypt or create a compressed password protect archive of the files. This method (Cryptkeeper) is perfect for this case when you need to be 100% sure no one will ever look at your files without knowing the password used there.

  • Use your computer folder / file permissions to deny access to your folder to other user.

The first involves making sure that the result cannot be opened by any user without knowing the password used.

The second will only change the file / folder privileges so that another user without rights cannot open it. The folder still exists, can be accessed by any user with sudo rights in your system or using a LiveCD and reading the partition. It is also simpler to implement and does not require that you type a password all the time you need to open / mount the encrypted folder / archive.

An easy and fast way to do so is using chmod to change the privileges for a file or folder.

Open a terminal and navigate to the place where your folder is, lets assume that the folder name is foo and that we are currently located where the folder is.

chmod 700 foo

will make foo only available for your eyes, its not encrypted (that is also possible) but only your user (and or a user with sudo privileges) can read or open that file / folder.

You can also do it graphically by right clicking on a file or folder and changing its permissions manually. In the example below you as owner have all privileges and you deny any other group or user from accessing, reading or modifying that file / folder

enter image description here

For more information about file / folder permissions visit the Ubuntu Understanding and Using File Permissions wiki page.

  • +1 can't go wrong with those elusive yet simple solutions. – Aaron Feb 16 '12 at 1:03
  • Sounds great, but doesn't make much sense. How do I simply "change the privileges" for a while or folder? – Gonzoza Feb 16 '12 at 7:12
  • You're dealing with newbies here. What does "using the command" mean? If I click on a folder, then how do "use a command"? – Gonzoza Feb 16 '12 at 9:50
  • I have added that to the answer also, right click a folder and go to the permissions and have a look at it. The example given would make the file / folder only accessible by you or a user with sudo rights. It is the same as issuing chmod 700 <folder_name> in a terminal. – Bruno Pereira Feb 16 '12 at 10:01
  • Brilliant. I shall try that. EDIT: Hang on. Doesn't that only work if someone else is logged on to my PC? Right now, I am logged on - and am the only user - so therefore, I can access all those folders without typing in a password. – Gonzoza Feb 16 '12 at 12:55

You can try Vault, recent project by an ubuntu-gr member (greek local community).


sudo add-apt-repository ppa:vault/ppa
sudo apt-get update
sudo apt-get install vault

It's a gui utility for encfs (package in repositories). I quote the package description:

$ apt-cache show encfs
Package: encfs
Description-en: encrypted virtual filesystem
 EncFS integrates file system encryption into the Unix(TM) file system.
 Encrypted data is stored within the native file system, thus no
 fixed-size loopback image is required.
 EncFS uses the FUSE kernel driver and library as a backend.
Homepage: http://www.arg0.net/encfs

You create a mountpoint/folder which you can then close or delete. If you close it, you need a password to open it.

    ppa does not exist anymore. – user4381 Dec 20 '16 at 14:51

Another way, depending on your needs is to archive the folder as a password protected zip file.

This is similar to another question about password protecting files.



You can use CryFS:

cryfs basedir mountdir

It is used by default in KDE Vaults and is particularly interesting if you synchronize the encrypted content over Dropbox, Freefilesync, rsync or similar software, because it keeps its data in small encrypted blocks and changing a small file results in only a small amount of data to be re-uploaded.

  • I would advise against cryfs because it doesn't support (standard Unix) hard links. – arielf Jan 14 '19 at 22:56

    Doesn't that depend on your use-case though? I guess don't use it for anything that requires a hard link? – RoundDuckMan Feb 28 '19 at 20:17
